Rate Versus Rhythm Control for Atrial Fibrillation.
Cardiol Clin. 2014 Nov;32(4):521-531
Authors: Halsey C, Chugh A
Treatment of patients with symptomatic atrial fibrillation (AF) with antiarrhythmic drug therapy in general improves their symptom scores and exercise tolerance; however, large randomized trials have failed to show a mortality benefit with a rhythm-control compared with a rate-control strategy. Catheter ablation in patients who have failed or not tolerated medical therapy has been shown to alleviate symptoms and improve quality of life. However, catheter ablation cannot undo the structural remodeling that contributed to the arrhythmia in the first place. Patients should be alerted to modifiable factors that may decrease the likelihood of unchecked structural remodeling and AF recurrence.
